This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

DFS DISC PARTITIONING
~~~~~~~~~~~~~~~~~~~~~
By Richard Dimond
This program was published in the Micro User, November 1991 to enable you
to split a disc into several parts. As published, it asked for all the
data to be entered individually. This could be very tedious if there are
several parts to be entered. I have simplified this by arranging that the
data is entered into two REM lines at the end of the program. This will
then set up both sides of a disc by running the program twice and simply
entering the drive numbers.
The REM lines consist of -
Number of Parts, Titles.... , Part sizes....
The part sizes are the number of tracks and the total for a 40 track disc
is 38 and for an 80 track disc it is 78. The last part is calculated as
the remainder after totalling the previous sizes.
The program should allow 12 letter titles but I have found that only 7 are
allowed. I know that the orininal program is correct as I have checked it
with the checksums given. Also, the titles do not seem to be printed as
they should be when the parts are catalogued. These comments do affect
the running of the program.
When run the program first asks for the drive number. The disc is then
checked and, if this is OK, it will tell you if it is 40 or 80 track. If
the disc is faulty, you are asked to re-format it. This part is as the
original program.
The data lines are then read. If the drive is 0 or 1 for side 1, the
first REM line is read and, for drives 2 or 3, the second REM line is
read.
After the disc is set up, there are two files in each part which must not
be deleted. 'PART' is the M/code for selecting the parts and is written
to &900 and '!DUMMY!' is the catalogue information.
To make a backup copy, you must set the disc to the final part as the disc
appears to be unformatted beyond the part selected.
